Wanted to declare a local variable inside a static method. main().
Here is what my code looks like -
Code:
class Operator
{
static int a;
public static void input() {
Scanner in=new Scanner(System.in);
System.out.println("Enter the number:");
a=in.nextInt(); //this is nextInt and NOT Nextint
}
public static void output() {
System.out.println("Number is:" + a);
}
public static void main (String[] args) throws java.lang.Exception
{
// your code goes here
input();
output();
}
}
Is it something I am doing right?
Any Sugession would be helpful
It may technically do what you want, but that's bad style. Static values should usually be avoided because they're really just global variables, which are very easy to accidentally misuse and generally make code hard to reason about.
ok, Understood!
Thanks for the reply.
I need your view on this too, I am Declaring a Static Variable in Java
Example:
Code:
public class Scaler {
//Creating two static members
static boolean check;
static int number;
public static void main(String[] args) {
System.out.println(Scaler.check); //Default value is false
System.out.println(Scaler.number); //Default value is 0.
}
}
Output:
Code:
false
0
Is this the correct way?
It's valid code. Whether it's reasonable for what you want in any given situation is impossible to say given such a contrived example.
